I've got the same problem in Ubuntu 13.04. After login, I get a blank screen for about a second, then it goes back to lightdm. Removing either .ICEauthority or .Xauthority solves the problem. The problem reappears (to me) seemingly random, so not necessarily after each successful login.

Often when I log in, after entering the password the screen gets black and within one second I am back in LightDM. I have to enter my password three or four times until getting a successful login. Logging in right after reboot works more often. Logging into the guest account always works. There are no messages in .xsession-errors. /var/log/syslog adds the following lines after pressing Enter after entering the password until LightDM re-appearing: First failed attempt: Sep 21 13:28:05
